Ive never been to Yosemite, but that looks like a great kit! I think from those I would use the 12-24mm and 31mm the most, and then the 77mm. Or the 18-135mm is the weather is bad (if you have WR camera)!
I usually go to parks like that with Samyang 14mm, a prime in the 28 - 50mm range (depends how I feel, where Im going - honestly, I would love FA 31mm), and then 100mm macro (works as landscape lens, as well). This is the kit that I like, as it is very versatile, but still not too heavy to carry around.
